When volatile, oil-based additives enter the dry-air circulation system, manufacturers should use specialized oil-resistant dehumidifiers for oily plastic resin drying instead of conventional 3-in-1 dryers. Operators should also follow the material supplier’s recommendations when setting the resin temperature and residence time to control oil contamination while maintaining stable, low-dew-point airflow. For applications involving oily plastic… Continue reading How Should Oily Plastic Resin Drying Be Done Before Injection Molding?

During production, if your Cartesian Coordinate robot arm suddenly stops moving or its operating speed slows significantly, the problem is often in the pneumatic circuit controlling the auxiliary arm, gripper, wrist, or related mechanisms. For pneumatic operations, you should prioritise troubleshooting the following three causes: The following troubleshooting steps apply to abnormal movements related to… Continue reading Why Is My Cartesian Coordinate Robot Arm Not Moving or Moving Slowly?

Although thin-walled plastic parts are rigid enough to be ejected from the mold cavity, they remain hot and relatively soft, so they cannot withstand concentrated gripping forces, excessive acceleration, torsional stress, or imprecise removal paths. This places extremely high demands on automated removal technologies in thin-wall injection molding. Cartesian injection molding robots must not only… Continue reading How Should Thin-Walled Plastic Parts Be Removed Without Deformation After Molding?

When the injection molding cycle time gradually increases during production, most operators tend to blame the injection molding machine. However, in this case, we need to analyze and identify issues with auxiliary equipment other than the injection molding machine. The auxiliary equipment surrounding the injection molding machine continuously determines the various conditions entering the molding… Continue reading Why Does Injection Molding Cycle Time Gradually Increase During Production?

Even when an injection molding machine is equipped with a sophisticated automatic material loader, a material shortage alarm may suddenly be triggered during the automatic feeding process. In many cases, the problem is not a shortage of resin at the factory, but rather the automatic feeder’s inability to deliver sufficient material to the injection molding… Continue reading Why Does an Injection Molding Machine Run Out of Material During Automatic Feeding?

When molds become heavier, wider, or deeper, or require a larger projected area, the key consideration is no longer simply whether the plastic molding machine can provide sufficient rated clamping force. It is also essential to ensure the clamping force is evenly distributed across the large platen to provide adequate mold mounting space and opening… Continue reading Direct Pressure vs. Toggle Clamping: Which Is Better for Large Molds?

In the daily operations of an injection molding plant, drying plastic resin often consumes the most energy because a dehumidifying dryer does more than heat plastic pellets once. It must continuously heat the resin, circulate large volumes of air, remove moisture, regenerate the dehumidifying medium, and typically also maintain the material’s temperature. At the same… Continue reading Why Does Plastic Resin Drying Use So Much Energy in Injection Molding Plants?

Following the successful deployment of virtual simulation data applications, Topstar has once again filled a critical gap by establishing real-machine data collection capabilities. This real-machine multi-modal data collection system is a core component of Topstar’s “Scene + Robot + Data + AI Model” framework. It bridges the data gap between hardware terminals and intelligent algorithms,… Continue reading Breaking Through the Full Scene-to-AI Link! Topstar Industrial Data Collection Matrix Achieves Major Technical Breakthro

For thick-walled parts, mold temperature control is more than reaching a set temperature. Rather, it involves removing and redistributing large amounts of heat while keeping the mold surface uniformly temperature throughout each molding cycle. Compared to thin-walled parts, thick-walled plastic products contain more molten material per unit area. As a result, more heat accumulates in… Continue reading Why Do Thick-walled Parts Need Higher Mold Water Flow?

When selecting a chiller, customers often compare cooling capacity and compressor types, or focus on whether the unit is air-cooled or water-cooled. However, another design difference directly affects installation: the evaporator cooling method. For Topstar chillers, the main distinction between shell-and-tube chillers and coil heat chillers is the evaporator cooling method. The evaporator structure determines… Continue reading Differences Between Shell-and-Tube Chillers and Coil Heat Chillers

Topstar Cartesian robots reserve additional I/O capacity beyond the signals used by the standard program. Based on the standard control configuration, users still have room to expand by at least 11 input and 11 output channels. Although the standard program supports 4 vacuum grippers and 4 fixtures, the control architecture can be expanded to support… Continue reading How Does IO Expansion Make Cartesian Robots More Flexible?

For most injection moulding applications, a standard 120°C mould temperature controller provides a sufficient temperature range. However, certain engineering plastics, precision components, and injection moulding processes with extremely high quality requirements demand higher, more stable mould temperatures. In such cases, if the equipment operates near the upper temperature limit of a 120°C system, it may… Continue reading When Should You Use a 160°C High-Temperature Mould Temperature Controller?
